Already standardized milk enters the tanks DONI®Tank/1/. Dry ingredients are added in doses using the module DONI®Dry Plus/2/. The mixture flows towards the pasteurisation module DONI®Therm/3/, where there is an integrated deareator and homogenisater. The mixture is then de-areated at 68°С, homogenised at 60°С and pasteurised at between 94°- 96°С. The minimum holding time recommended by DONIDO® is 5min, it can reach 30mins during certain productions. The high pasteurisation temperature and the continuous hold are a necessary precondition for good coagulum.
The pasteurised product is cooled to the required temperature for the fermentation process and is then fed into the process tank DONI®Process/6/ for coagulation. In the meantime, the appropriate quantity of starter culture is dosed and injected in line using the module DONI®Ferment Plus/5/ along with any liquid additives such as sterile jam using the module DONI®Liquid Plus/4/.
The process in the process tank DONI®Process/6/ is controlled and run with pre-programmed parameters according to product requirements and usually in an environment of sterile air at a pressure of 0,2 bar The finished product is cooled through DONI®Therm CH/7/ where it then goes into DONI®Process/8/ for temporary holding during packaging. To preserve the coagulum the product is transported with volumetric pumps or with the pressure of the sterile air. The packaging is carried out in the aseptic conditions of DONI®Pack/9/ in commercial packaging that is chosen by the client. The capacity of the manufacturing unit will be limited to the hourly productivity of the packaging machines and the working schedule.
